Moby, an apprentice magician, is a girl who is traveling to Ildernaja, a city with an adventurer’s guild, to become an adventurer.
One day, there are only a few days left until Ildernaja. Moby hears a rumor of a strange phenomenon on the island of Caundry, which is known as a port waiting for the wind.
It is called the “Great Calm,” and it is said that for five days out of the year, the wind stops blowing on the island.
